I cannot emphasize how p'od I am because of my uncles compy. As some of you know, it started doing random reboots and shutdowns. Well, I took it down to my compy shop, baffled, that it wasnt a virus or PSU gone bad. I had them check the CPU and mobo. They had said it was the mobo. I sent it in for an RMA, and got it back. Plugged it up and it worked, for about the first two times it was on. Then, the symptoms started again. I came here for help, and you guys said it was the RAM. I sent those in for RMA, and just barely got them today. It fired up once, then the symptoms arised AGAIN!!!!!! GAH!!!! I am ready to take a 12 gauge to it! Anyways, what to do?<br><br>
Specs:<br><br>
PentD 930<br>
G-Byte GA-8I945P-G<br>
Generic 430W PSU (I tested this in my sys, and tried the compy with my PSU, IT'S FINE)<br>
WD Caviar 250GB SATAII Drive<br>
Corsair VS 2GB Kit DDR2-667<br>
Asus Radeon X300 128mb PCI-e vid (could this be the culprit? I'm ready to take the oddest remedies right about now)<br><br>
I think that's about it... Thanks for ANY suggestions.

My first take would be the PSU. although it works in your rig, his demands more power (CPU!)<br />
<br />
Did you try your PSU in his rig?

How random are the reboots? If totally random, I again suspect the PSU. It might not be bad, but maybe just not enough juice for that rig (18A on 12V rail I guess??)<br />
<br />
If there is some pattern you might want to check temps.... <br />
<br />
Generally, a faulty video card should not result in random reboots. If that's the issue, the system tends to freeze instead of reboot.<br />
<br />
If PSU and Temps are ok, run memtest86 and check if the RAM is ok.

The reboots and shutdowns are more random than the most complex randomizer. I will, as I stated, check the PSU tomorrow. Right now, sleepy time.

Ok, switched out the PSU from the generic @Power 430W 20pin 17A on the 12V to a MSI 450W SLI-Ready 18A on 12V 24-pin ATX. Same thing. But I am going to take to another compy shop and have them run a full diag on this headache.

We have Dells at work that have what seems to be (at the moment) a(nother) Dell specific electrical fault that causes resetting or random shutting down.<br><br>
Check the capacitors on the mobo have perfectly flat tops and sides (well they are cylinders but you get what i mean).. if they are swolen in any way then this is causing your problem.

A sticking or defective case switch may cause that. Did you try disconnectiong it and start by jumping the 2 pins manually?

Just recently I was given a laptop to trouble shoot since it had the same symptoms as yours is. The cause was the hard drive. Basically the head kept getting stuck. Cuasing it to reboot. Why I dunno. If anyone could explain that .. much apretiated.<br />
<br />
Secondly I'd recomend booting into safe mode. Try doing something that would cause the comp to reboot. If it still reboots in safe mode. There is a possibility that its related to a corrupted file in windows (if thats what you are using).<br />
<br />
Thats my two cents. Hope it helps.

Hey peeps... I have another head scratcher for you.<br><br>
So far I have RMA'd the mobo and the RAM. I decided to give him the MSI PSU, better then the cheap-o crap right? I ruled out a shortage in the case. I have ruled out the PSU (underpowering). Some people suggested that the HD is frying. I think I'm gonna have to go with that one. When the comp is on, the HD is really trying to do something. I dont know what, but the head is moving like crazy. I did take it out of the case, tried another HD, and cleared the CMOS. It worked! For only about 5 min. The comp is sitting right next to me out of the case, please help.<br><br>
He is in town and would like to take it back tomorrow, but that may not happen if I have to RMA something else.

The HDD is not at fault. I tried it w/o the HDD and it still had the same symptoms. I'm getting annoyed.

I tried running it w/o vid, and it's a P chipset, it has no onboard vid.<br />
<br />
I tried running just the mobo with CPU and RAM. Ran fine for a couple of seconds, then shut off. What gets me is that I had it running just fine the other day.

Throw a live Knoppix disk in it and see if it acts up, if not you have a software issue.<br />
Unless it's the case switch and you have not tried bypassing it as I suggested.

</div>I did bypass the power switch. Nope. And the knoppix suggestion cant work because the mobo sometimes doesnt POST.

Man that is screaming vid card or mobo.....any other expansion cards running that could be causing a short?<br />
<br />
edit: also is it a passively cooled x300? those things are bad about overheating, I had one that if you put your finger on the heatsink it would burn the mess out of you.
